The invention consists in the combination of the slotted standard, the stationary blade, the movable blade, the pivoted connecting-rod, the crank, the shaft, the frame, the upper pulley, the band, the lower pulley, the wheel, and the bolt' with each other, as

hereinafter fully described.

A represents a standard or frame, to the lower end of which, in an inclined position, is

end of the shaft F that passes through a longitudinal slot in. the standard A, and revolves in hearings in the frame G. 1 To the shaft F, within the frame G, is attached a small grooved pulley, H, around which passes a band, I, which also passes around a larger pulley, J, attached to or rigidly connected with the Wheel K, the journals of which revolve in hearings in the lower part of the frame G. The wheel K is designed to 'roll along the ground at the side of the edge to be sheared and carry the machine forward, and at the same time by its revolution to work the movable blade 0. The

frame G is secured to the standard A by a bolt, L, attached to the frame G, and which passes through the slot in the standard A, and is secured in place by a nut, so that by loosening THEODOR SOETBEER.
